HBO’s Tennis Mocumentary Stars Game Of Thrones’ Kit Harington (Video)

Jon Snow might not know anything, but Kit Harington appears to be a man of many faces.

The “Game of Thrones” star is the co-lead in HBO’s new mock tennis dockumentary “7 Days in Hell” about the longest match in tennis history. Harington and Andy Samberg play Charles Poole and Aaron Williams, respectively — the two participants in the legendary match.

In the teaser trailer, the narrator describes the match as “two men stuck in eternal flames,” which is awkward because, as “Game of Thrones” fans know all too well, Winter is Coming.

Check out the hilarious trailer below.

The star-studded supporting cast includes Serena Williams, Lena Dunham, Will Forte, Karen Gillan, Michael Sheen, June Squibb, Soledad O’Brien, Howie Mandel, Fred Armisen and Mary Steenburgen.

“Game of Thrones” airs Sundays at 9 p.m. ET on HBO, while “7 Days in Hell” premieres July 11 on HBO.
